Morris Ld van 1 tonne carb gasket help
corrado vr6 - 8/5/15 at 09:43 PM

Hi there

A mate of mine is restoring a Morris LD van, when he bought it the carb had already been removed and the gasket lost. He's not sure what the gasket material would have been as the carb is bolted to the inlet manifold but also attaches strangely to the exhaust manifold too so the material would have to be heat resistant, the exhaust gasket which he still has is a leather like material.

Does anyone know what he could either make a gasket from or possibly somewhere he could buy the gasket, he's tried the eBay but to no avail.

Any help much appreciated

For those that don't know what one looks like here's a pic

The a series engine shared the exhaust and inlet manifold frome memory there was a bakolite type of spacer Im sure that it was a paper gasket that went between them all

When I worked in chemical plant manufacture we used a thick (3mm ish) gasket called Klingerit.
It was either pink paper clad or green.

Nowadays its referred to as asbestos free gasket.

I use a company called East Anglian Sealing Company or East Anglian Seals
or their website is easeals . Google will find it.
I believe they have CNC capability for cutting complicated shapes.

I built a little heating oil delivery tanker based on a 4x4 pick up a while back and needed several 1 off gaskets
resistant to fuel oil and they could not have been more helpful.

I've always found the Carburetter Exchange in Leighton Buzzard to be very helpful

The joint doesn't require anything fancy in the way of gasket material but there should normally be an asbestos (later plastic) spacer (about 6mm thick) between the carb and the manifold to prevent fuel vaporisation causing a vapour lock. On a lot of vehicles the joint would also incorporate a metal heat shield to help keep the carb float bowl cool.


A standard oil resistant gasket material is all that is require thickness required depends on the condition of the surfaces but I would suggest 0.8mm

Ebay Link suitable material

Have you got a picture of the offending item (preferably with something for scale)? I've got some boxes of ancient carb/exhaust gaskets somewhere.

Thanks for that link to eBay

I shall get a pic of the carb tonight when I see him but to give you an idea it's a rectangular gasket with 4 bolt holes
Dimensions 85 x 76mm with a big rectangular hole in the middle

Sounds familiar...

That's not the carb flange it is the hotspot, it should be a steel plate with a copper gasket on each side.

Nb steel plate. -- no hole in the middle

Ah ok this would make a lot more sense!
Any ideas where to get a copper gasket from or could he make one from some copper sheet?

Oh and what was the idea of the hotspot?
